DETROIT, MI -- While disgraced Detroit Mayor Kwame Kilpatrick begins the front end of a 28-year sentence in El Reno, Okla, his impact still ripples beyond the sturdy prison walls.

Kilpatrick's near-decade of corruption, which according to investigators began while he was a promising state representative in Lansing, will be the focus of CNBC's "Greed," a documentary-style program, set to air at 10 p.m. Wednesday.

Derrick Miller, Kilpatrick's friend and the right-hand-man in his administration, who accepted a plead deal and provided key testimony against his former boss, received a 12-month sentence to a halfway house Thursday. Miller was the last of the major players in the corruption case to receive his sentence.

Is it possible to run a criminal empire out of City Hall? That's exactly what Detroit Mayor Kwame Kilpatrick did during his six years in office. Once hailed as the "Hip-Hop Mayor" of this struggling rust-belt metropolis, Kilpatrick was in reality the leader of a cabal that cost the city millions of dollars. Throughout his tenure, Kilpatrick and his friends extorted city contractors, abused public funds, and turned the mayor's office into their own cash machine. But while the mayor counted his cash, it was a high-profile sex scandal with a city employee that ultimately brought him down. The trial and resulting publicity eventually exposed the mayor's greed for all to see.
